Expect Jonas Brothers: 3-D Concert Experience to top the box office this weekend with estimated ticket sales around $20 million. But with sold-out screenings and Disney promotional power, the flick won't come close to the opening of Miley Cyrus' Hannah Montana 3-D, which was marketed as a limited engagement. "Honestly, I don't think it's disappointing at all," a rival exec told Deadline Hollywood Daily. "Many had unrealistic expectations for this pic at $40+M." With no real competition, the tween-targeted boy band should rest easy. Overall, estimates put this weekend's box office tally at $105 million—up 20% from last year, and continuing a trend of popularity despite the recession.
